电荷放大器由电荷变换级、适调级、低通滤波器、高通滤波器、末级功放、电源几部分组成。
But the present charge amplifier remains high price for its complicated circuit design, so the performance price ratio is not very ideal. All these factors seriously influence the widespread use of piezoelectric accelerometer.
但是传统的的电荷放大器电路设计复杂、价格较高、性价比不理想,严重影响了压电加速度传感器的广泛使用,所以研制一种性价比较高的、实用的电荷放大器非常有必要。
